Embodiment Construction

[0016]With reference to FIG. 1, a safety switch in accordance with the present invention is mounted on a power strip having a power-supplying circuit and may activate or cut off the power-supply circuit.

[0017]The safety switch comprises a housing (10), a first leg (21), a second leg (22), a third leg (23), a bimetal plate (24) and a cover (30).

[0018]The housing (10) is hollow and comprises a top, a front, a bottom, a space (11), an opening (12), multiple gaps (13) and a button (14). The space (11) is defined in the housing (10) to contain elements for protecting the switch from overloading. The opening (12) is defined in the front. The gaps (13) are respectively defined through the bottom. The button (14) is mounted on and protrudes up from the top of the housing (10) to activate or cut off power-supplying circuit and comprises an arm (141). The arm (141) extends form the button into the space (11).

[0019]The first leg (21) is mounted in one of the gaps (13) and comprises a top, a ve...

Abstract

A safety switch has a housing, multiple legs and a cover. The housing is hollow and has a space, an opening, multiple gaps, a bottom and a front. The space is defined in the housing. The opening is defined in the front. The gaps are respectively defined through the bottom. The legs are respectively mounted in the gaps and each has a vertical edge. The cover is mounted on the opening of the housing and has the inner surface. The inner surface tightly abuts and holds the vertical edge of the legs to hold securely the legs in the gaps. Therefore, the safety switch has a low cost and is compact.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a switch, and especially to a safety switch that is compact and has a low cost.[0003]2. Description of the Related Art[0004]With reference to FIG. 4, a conventional safety switch comprises a housing (50), a cover and multiple legs (60). The housing (50) is hollow and comprises a front, a bottom, a space (51), an opening (52) and multiple gaps (53). The space (51) is defined in the housing (50) to contain elements for protecting the switch from overloading. The opening (52) is defined in the front. The gaps (53) are respectively defined in the bottom and each comprises a mounting tab and an inner surface. The mounting tab is formed on and protrudes out of the inner surface. The cover is mounted on the opening (52) of the housing (50) and comprises multiple mounting tabs and an inner surface. The mounting tabs are formed on and protrude out of the inner surface of the cover and respectivel...
